Yu Li commented on FLINK-14846:
-------------------------------
Since the [rocksdb PR|https://github.com/facebook/rocksdb/pull/5670] on javadoc
correction already accepted and merged by rocksdb community, I believe it's
necessary to also update our documentation accordingly. Please open a PR for
the change [~yunta], thanks.
> Correct the default writerbuffer size documentation of RocksDB

> Key: FLINK-14846
> URL: https://issues.apache.org/jira/browse/FLINK-14846
> Project: Flink
> Issue Type: Bug
> Components: Runtime / State Backends
> Reporter: Yun Tang
> Priority: Major
> Fix For: 1.10.0
>
>
> When introduce {{RocksDBConfigurableOptions}}, the default writer buffer size
> is referenced from RocksDB's javadoc. Unfortunately, RocksDB's official
> javadoc was described incorrectly as {{4MB}} for a long time until I create a
> [PR|https://github.com/facebook/rocksdb/pull/5670] to correct it. This also
> leads [our
> description|https://ci.apache.org/projects/flink/flink-docs-stable/ops/config.html#state-backend-rocksdb-writebuffer-size]
> of default write-buffer size not correct, we should fix this to avoid to
> mislead users.
